Material examined

Centre-West Ivory Coast, Oumé (6 u 379N, 4 u 409W). Leg. J. Tondoh, August 2004. Teak plantation HNHM AF/5093, 2 ex. , Fallow AF/5094, 2 ex., Degraded forest AF/5095, 1 ex.

Diagnosis

L. 110–167 mm, D. 4–7 mm. No. segments 130–221. Colour greenish. First dorsal pore in 12/13. Clitellum K13–19. R 14 unpaired, ventral-median. Prostatic pores 17, 19. Spermathecal pores 7/8, 8/9, spermathecae with rounded ampoule and longer duct bearing a multilobed diverticulum. Gizzard in 5–6, last pair of hearts in 13. Penial setae uniform, covered by an undulated membrane, L. 2.5– 3 mm, D. 0.03 mm. Tip funnel-shaped, ornamentation lacking.

Remarks

In the original description ( Sciacchitano 1952) the female pores are mentioned as paired openings, but on the drawings of Omodeo (1955a, p 226, Figure 6a) depiction is as a single ventral-median organ. In our material the female pore is also single and this casts doubt on the correctness of the original description on this point.
